The present invention relates to packages for sterile pointed objects, such as needles, and more particularly to thermoformed blister packages for such objects.
Blister packs for needles are well known and used due to their effectiveness and economy. Pointed devices, such as needles, especially heavy ones, can puncture their packaging during shipping and handling. In the case of medical devices, punctures in the packaging renders them non-sterile and the sharply pointed devices can pose a safety hazard. In the past, this problem was attempted to be solved by incorporating snap-fit retainers or undercuts in the blister pack to establish an interference/friction fit to retain the pointed object in place within the pack and prevent punctures. In order to make the snap-fit retainers strong enough to hold needles in place within the pack, they must exert a strong grip on the needle which has to be overcome by the user when the needle is removed from the package. Because the use of snap-fit retainers requires a mechanical interaction between the package and the needle demanding close tolerances, a specific package has to be used with each different size needle. Due to the surface smoothness of the plastic material used in forming blister packs and the surface smoothness of needles, along with the high density of the needles, even a tight fit between the retainer and needle does not insure that the needle will not become dislodged given a sufficiently large shock in a critical direction. A known alternative technology is to use needle caps that are friction fit over the point of the needles before packaging to prevent the points from puncturing the packaging during shipping and handling. Protective caps, however, are difficult to remove and complicate time-critical surgical procedures.
The problems and disadvantages associated with the conventional techniques and devices utilized to hold pointed objects are overcome by the present invention which includes a package having a tray portion with an internal hollow delimited by a bottom surface and a sidewall. The internal hollow receives the pointed object therein and a removable support member extends substantially parallel to the bottom surface over the internal hollow. A point guard depends from the support member towards the tray proximate the sidewall, with the point guard interposable between the sidewall and a point on the pointed object to be held.
For a better understanding of the present invention, reference is made to the following detailed description of an exemplary embodiment considered in conjunction with the accompanying drawings, in which:
FIG. 1 is an exploded view of a needle package in accordance with an exemplary embodiment of the present invention;
FIG. 2 is a plan view of a cover portion of the needle package of FIG. 1;
FIG. 3 is a plan view of a tray portion of the needle package of FIG. 1;
FIGS. 4 and 5 are diagrammatic views of a needle package in accordance with the prior art; and
FIGS. 6 and 7 are diagrammatic views of the needle package of FIG. 1.
FIGS. 1-3 show a needle package 10 which is preferably thermoformed or injection molded from plastic, such as polypropylene, polystyrene, polyethylene and equivalents thereof to yield a “blister” type package. The needle package 10 has a tray portion 12 and a cover 14. The tray 12 has a plurality of needle channels 16 a, 16 b, 18 a, 18 b for receiving needles therein. The needle channels 16 a, 16 b and 18 a, 18 b are juxtaposed end-to-end to form an arcuate shape that may accommodate an arcuate needle extending through both, e.g., 16 a, 16 b. Alternatively, channels 16 a, 16 b could be straight for holding straight needles. A series of raised areas 20 a, 20 b, 22 a, 22 b, 24 a and 24 b define and separate the channels, 16 a, 16b, 18 a, 18 b. A central recessed surface area 26 positioned between and below the channels 16 a, 16 b, 18 a, 18 b, facilitates a user in grasping needles that are present in the channels, e.g., 16 a, 16 b. A left recessed surface area 28 is provided at one end of the channels 16 a, 18 a and a right recessed surface area 30 is provided at a distal end of channels 16 b, 18 b.
The cover 14 has a substantially flat panel 32 into which is formed a pair of gripping recesses 34, 36, two pairs of needle abutments 38 a, 38 b and 40 a, 40 b, and three end stops or point guards 42, 44, 46. The flat panel 32 functions as a support member for end stops 42, 44, 46 and may be perforated to decrease material usage. The gripping recesses 34, 36 are positioned and dimensioned to be received proximate the central recessed area 26 and are intended to accommodate the fingers and thumb of a user to aid in grasping and removing the cover 14 from a position covering the tray 12. The gripping recesses 34, 36 may be disposed on the cover 14 in a position offset from the channels 16 a, 16 b, 18 a, 18 b. In this manner, the gripping recesses can extend down further toward the central recessed surface area 26 without interfering with the needles stored in the package 10. The needle abutments 38 a, 38 b and 40 a, 40 b are aligned with the channels 16 a, 16 b and 18 a, 18 b, respectively, extending downward towards the channels 16 a, 16 b, 18 a, 18 b and any needles contained therein to a selected extent for the purpose of constraining the upward motion of any needles contained in the package 10 to a selected degree. End stop 42 is shaped and positioned to be received proximate left recessed surface area 28 and end stops 44 and 46 are received proximate right recessed surface area 30 when the cover 14 is placed on the tray 12 after the needles have been loaded into the tray 12. When so placed, end stop 42 extends across channels 16 a and 18 a proximate left recessed surface area 28 and end stops 44 and 46 block channels 16 b and 18 b proximate right recessed surface area 30. The purpose of this juxtapositioning shall be explained below.
Tray 12 has a peripheral glue flange 54 for receiving a sealing membrane 60 (See FIG. 6) formed from aluminum, Tyvek or other conventional covering material used on blister packages which such sheet is adhered to the glue flange 54 by adhesive or plastic welding. An inner edge 56 of the glue flange 54 defines an inner peripheral shape that approximates the outer peripheral shape of the cover 14. A peripheral sidewall 62 extends between the recessed surface areas 26, 28, 30 to the inner edge 56 of glue flange 54.
FIGS. 4 and 5 illustrate a prior art needle package having a needle retainer B for holding a needle C. In transit or during handling, the needle C can be displaced from the retainer B and pierce the wall of the package A.
FIGS. 6 and 7 diagrammatically illustrate a portion of a needle package 10 in accordance with the present invention for holding a needle 58 and having a tray 12 with a recessed surface area 30. The needle 58 is received in a channel 16 b. A cover 14 includes a needle abutment 38 b for restraining the upward movement of the needle 58 and an end stop 44 which inserts into the recess 30. The tray 12 and cover 14 are covered by a sealing membrane 60 adhered to glue flange 54, such that the sealing membrane 60 prevents the cover from lifting away from the tray and allowing the end stop 44 to escape from the recess 30. In this manner, the end stop 44 is held in front of the needle 58 despite there being some clearance between the cover 14, the tray 12 and the sealing membrane 60. In order for the needle to penetrate the tray 12, it must first penetrate the end stop 44 which is defined by descending and ascending walls 64, 66 respectively, an unlikely occurrence. As can appreciated from FIG. 7, the fact that there is some clearance between the components of the package 10, e.g., between tray 12 and cover 14 and between cover 14 and sealing membrane 60 and because there is no requirement for an interference fit between the needle 68 and the package 10, needles of various sizes and shapes can be accommodated therein.
FIG. 7 depicts a tapered needle 68 in place of the straight needle 58 shown in FIG. 6. The loose fit between the tray 12 and the cover 14 permits the cover 14 to be easily withdrawn from the tray 12 to access the needle(s) contained therein. After the cover 14 is removed from the tray 12, the needle(s) contained therein can be easily removed by grasping them with the fingers since there is no frictional restraint to overcome. If desired, the tray 12 can be inverted over the sterile field to permit the needle(s) contained therein to be emptied from the tray 12 onto the sterile field.
It should be understood that the embodiments described herein are merely exemplary and that a person skilled in the art may make many variations and modifications without departing from the spirit and scope of the invention as defined in the appended claims.
